LOG-LOADING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 630,105, dated August1, 1899.

Application filed April 1l, 1899. Serial No. 712,599. (No model.)

To all whom t may concern:

Be it known that I, HORACE BURTON PHIL- LIPS, residing at Suffolk, inthe county of Nansemond and State of Virginia, have Iliade certain newand useful Improvements in Log- Loading Apparatus, of which thefollowing is a specification.

My invention is an improvement in apparatus for use in loggingoperations, and includes means for handling the logs and devices wherebythe log-handling means supported on a suitable platform may be adjustedby means of vertically-movable legs on the said platform, so thelogging-cars may pass freely under the said platform, or the platformmay be'lowered onto one of said cars, so it can be transported frompoint to point as may be desired.

The invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described, and pointed out in theclaims.

In the drawings, Figure l is a side View, partly broken away, of myapparatus. Fig. 2 is a detail vertical section on about line 2 2 of Fig.l. Fig. 3 is a detail cross-sectional View on about line 3 3 of Fig. l.Fig. 4 is a sectional plan view of the apparatus, and Fig. 5 is a detailperspective view showing portions of the base and guideway uprights.

The platform A is adapted to support the mechanism for handling logs,which may consist, as shown, of a swinging crane B, having ahoisting-rope C, and a stationary engine, including a drum D, foroperatin g the hoistingrope, a suitable boiler E being provided forgenerating steam. Mauifestly the mechanism for handling the logs may bevaried, and I do not desire in the broad features of my invention to belimited to the special construction of such mechanism shown and beforedescribed.

The platform A is adapted to rest upon a logging-car G and is providedat its opposite sides with legs H, which are movable verticallyalongside the car and may be set to bear upon the surface of the groundin order to support the platform A up above and clear of the car whendesired. These legs H possess several main characteristics, among whichmay be named their independence of movement, so any one leg may be setup or down independently of the others, and also the arrangement of thesaid legs to move vertically up and down, so they can be operated toraise the platform A directly up from and lowerit upon the bed of a carwithout giving to such car-bed any motion in one direction or the other,such as might result from the swinging of the platform A down onto thecar-bed in any direction of movement except on a vertical line.

In practice the legs may be moved up or down by means of screws or othermechanical powers properly applied; but I prefer to operate the leg bymeans of Huid-pressure, such as air, steam, or water. I

In the special construction shown I provide at the opposite sides of theplatform A, near its opposite ends, vertical guideways for the legs,such guideways including the upright beams I, mounted on the platformand spaced apart, the plates J, connecting the uprights I and arrangedto inclose the leg and the portion A' of the platform A, which projectsbetween the uprights I and is spaced apart from such uprights at theirlower ends and forms the recesses a, in which operate the side bars ofthe legs. The legs are formed with the side bars H', connected by thefoot-piece H2 and by the bracket H3 at the top, and these legs operatein the guideways between the uprights I and within the plates .I,withthe side bars H moving in the recesses a in the platform A, as shown. Bythis construction the legs are firmly connected with the platform, areaccurately guided iu their vertical movements, and form no obstructionwhen the legs are adjusted up alongside the platform when it is desiredto support such platform on a logging-car for the purpose oftransporting the platform. The uprights I-I, being spaced apart,alsopermit the cylinders K to be located between the uprights H', or, inother words, fairly within the legs, so the power exerted on the pistonmay operate in a direct line. The pistons L operate in the cylinders Kand have their rods extended upward and connected with the bracket II3at the upper ends of their respective legs. Fluid is admitted to thecylinders, such admission being controlled independently at eachcylinder by valves. It is preferred to provide one Ivalve at each end ofthe cylinder, so the fluid may IOO be admitted above or below the pistonto positively operate the leg either up or down, as may be desired. Itwill be understood that by positively operating the legs upward they maybe drawn out of the mud or bog in which they may sometimes be set inoperation. The Huid, which may be air, steam, or water, as beforesuggested, may be supplied by a suitable pump M or otherwise, as may bedesired.

By operating each of the legsindependently it is obvious the platformmay be readily adjusted to a desired level position, with the legsresting on uneven ground or on marshy or other soft ground, in which thelegs may sink to different depths.

Having th'us described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

operating between the upright on the platform and the recesses formed insaid platform and within the side plates connecting the u prights, thecylinders li ttin g between the side bars of the legs and attached tothe platform, the pistons operating in the cylinders and having theirrods connected with the legs,

and means for controlling the passage of liuid to said cylinderssubstantially as set forth.

2. In an apparatus substantially as described the combination of theplatform, the legs movable 4up and down thereon, the cylinders arrangedwithin said legs and the pistons operating in said cylinders andarranged to operate the legs substantially as set forth. 3. In anapparatus substantially as de-v scribed the combination of the platformhaving at its opposite sides upright guideways comprising upright beamsspaced apart and connected substantially as described, the legsoperating in said guideways and means for operating said legssubstantially as described.
